Because of the lnounting of the ,stein llof the valve 9, it will befunderstood that the same will be, at all times, retained in vertical aligninent with its seat and in consequence, movement of thel reference Will designate correi samethereonto, with the arise of any emergency, will be ensured.

In order that motion may be imparted to the valve 9 with the occurrence of an abnormal condition, an operating shaft 12 is mounted at one end in suitable bearings in the vertical portion of the bracket 5 as at 13, while the opposite end thereof extends through a combined journal box and pack! ing 14 to a point exteriorly of the still 1. In this connection, it is to be noted that the inner end of the operating shaft 12 is mounted upon the vert-ical portion of the bracket 5 in a laterally off-set fashion, by reason of the arrangement of the laterally extending arm 13 secured at one end to said vertical portion of the bracket 5 by means of Y bolts or similar fastening devices 15.

' ating shaft 12, reciprocal motion will be imparted to the valve 9 by way of its stein 11, the arms 16 and the connecting links 17, hence, moving the samev onto or from its seat as may be desired. 1

Fixedly mounted upon the squared outer extremity 2O of the operating shaft 12 is an arm 21 carrying the weight 22 upon one end thereof, while the opposite end is apertured and receives a hook 23 `in the same adapted to retain one end of a fusible link 24, t-he opposite end of which is engaged with a hook and eye arranged in the upper side of the counter weight 25.

Because of the counterweighted arrangement of the arm 21, it will be understood` that its normal position will be that as shown in the Figure 3, the weight 25 counterbalancing the weight 22 and normally retaining said arm in a substantially horizontal position, whereat the arrangement of the arms 16 will be such as to retain the valve 9 in its uppermost position and spaced from the outlet 2 of the still 1, permitting the tar-like residue to be pumped from the still during its process of distillation.

The operation of. the device may be reviewed as follows: o

' As above stated, under normal conditions, the valve 9 is retained in its uppermost position thus giving the tar-like residue free access to the outlet opening 2 from whence it is directed into the conveying pipe 3. Should, however, the conveying pipe 3 lbecome broken, a portion of the residue will immediately flow through the fractured portion thereofand, upon contacting with be rocked in a direction to impart a down-` ward thrust to the coupling links V17 and since these links are connected to the arms 16 and to the intermediate portion of the valve stem 11, the valve9 thereupon will,` immediately move downwardly and over the valve seat formed in the upper portion of the nipple 41, thus positively closing the outlet 2 of the still and preventing anyV further pumping ofV residue into the pipe 3. The device, of course, may be. readily reset by merely moving the now unweighted end of the arm 21 downwardly to a substantially horizontal position, as shown in dotted lines, in the Figure 3 and connecting the counterweight 25 to the hook 23 through the medium of a new fusible link or coupling24. y Y" w Manifestly, theV construction shown is capable of considerable modification and such modification asis within the scope'jorf my claims, VI consider within the spirit of my invention. g

I claim: 1. In. combination withk a container having an outlet openingtherein, a valve for closing said outlet opening, afshaft mounted in said container hav'ingfonev end connectedto said valve for.l imparting reciprocal movement to the same, an arm, ixedly mounted ,on the outer end of said shaft exteriorly of the container havingone'end weighted," a counterweight, and a fusible link for connecting the counterweight to the remaining end of said arm. i

2. In combination with a .container having an outlet opening therein, a valve for closing said outlet opening, a shaft mount-V ed in saidcontainen right angularly disposed arms inedl'y mounted upon one portion of said shaft, connecting links pivotally connected to the freeends of-said arms, a stem extending vertically from said valve and pivotally connected ,to thefree ends of said links, an arm iiXedly mounted on the other end yof the, shaft, having one end weighted a counterweight, anda fusible Y link Vfor connecting the countervveight to theremaining end' of said arm. Y

3. In combination with a container having an outlet opening therein, a substantiallyv L-shaped, bracket arrangedV in and secured to portions of said container, a plug valve for closing said outlet opening, the

stem of said valve being disposed vertically and slidably engaged with portions of said L-shaped bracket, a shaft mountedat one end upon the vertical portion of said bracket Vand having its opposite end eX- tended through one side Wall of the container to a point exteriorly of the same7 substantially right angularly disposed arms tixedly carried upon the inner portions of l0 said shaft, links pivoted to the outer ends of said arms and at their remaining ends to the intermediate portion of the valve stem, an arm Xedly mounted upon the outer extremity of said shaft, a Weight on one end of said arm, a counterweight, and a fusible link for connecting said counterweight to the free end of the arm.

In Witness whereof I have hereunto set my hand.
